Abstract
A system and method for a resistor for detecting the relative level of moisture content in a humid environment. The resistor has a first layer of conductive material on a top surface of a substrate having a bend. The conductive material is exposed to atmospheric conditions. The first layer of conductive material has a static condition moisture content and a measurable electrical resistance that changes predictably when the amount of moisture content in contact with the first layer of conductive material changes from the static condition. The change of resistance of the first layer of conductive material corresponds to a change in the moisture content in contact with the first layer of electrically conductive material.
